## How to calculate a downward slope

Posted on 04.06.2018 by Louanne

In a nutshell, the slope of a line is simply the change in the y-values vs. I also have the surface normal for each polygon, and am familiar with dot and cross products. Draw dots on the graph to represent these points, and note their coordinates.

I can also calculate a simple angle value for the polygon by taking the arccos of the dot product. Solve a coordinate given the slope and distance from a point. I have searched many forums, including this one, but can't find the answer.
